is a procedure where participants are assigned to either the treatment or control group on the basis of chance, like the flip of a coin.

This procedure is known as Random Assignment. It is commonly used in experimental research designs to ensure that each participant has an equal chance of being placed in any group. This helps to reduce bias and increase the validity of the results. Here are the steps:

1. Identify the participants: The first step is to identify the individuals who will be participating in the study.

2. Define the groups: Next, define the treatment and control groups. The treatment group will receive the intervention or treatment being studied, while the control group will not.

3. Assign participants to groups: Use a method of chance, such as flipping a coin, to assign each participant to either the treatment or control group. This ensures that the assignment is random and not influenced by any outside factors.

4. Conduct the study: Once the participants have been assigned to their groups, the study can be conducted. The results from the treatment and control groups can then be compared to determine the effectiveness of the intervention or treatment.

5. Analyze the results: After the study has been conducted, the results are analyzed to determine if there is a significant difference between the treatment and control groups. If there is a significant difference, it can be concluded that the treatment had an effect.
